Ma Guohan (1794-1857), courtesy name Ma Cixi 馬詞溪, style Zhuwu 竹吾, was a late Qing period 清 (1644-1911) collector and publisher. His ancestors came from Zhangqiu 章丘, Shandong, but later moved to Licheng 歷城 near Jinan 濟南. As a young boy Ma Guohan accompanied his father to Shanxi to visit important libraries. In 1831 he earned the juren degree and was appointed magistrate of a series of districts in Shaanxi. After a phase of recreation he became prefect of Longzhou 隴州, Shaanxi. Ma Guohan was such an ardent collector of books that he spent half of his salary to increase his library, the famous Yuhan shanfang 玉函山房 "Mountain Studio of the Jade Case". He was especially interested in text-critical editions and fragments of ancient texts. Until 1849 he had acquired more than 57,000 juan "scrolls" of books that were listed in his catalogue Yuhan shanfang cangshu bulu 玉函山房藏書簿錄. This 25 juan long catalogue was organised like Chao Gongwu's 晁公武 Junzhai dushu zhi 郡齋讀書志 and was divided according to the four traditional categories of literature. A great part of his books were encyclopedias that were immensely helpful for his own research in transmitted fragments. The result of this research is the collectaneumYuhan shanfang jiyi shu 玉函山房輯佚書 that includes the fragments of 594 lost books written before the Song period. It is the earliest private compilation on literary fragments. Some contemporaries doubted that Ma Guohan was the compiler of this collection and attributed it to Zhang Yongyuan 章宗源. Ma Guohan did not have a son, and so his library went lost. His private writings include the books Nongyan 農諺, Xia xiaozheng shizhu 夏小正詩注, Yuhan shanfang wenji 玉函山房文集 (collected prose writings), Yuhan shanfang shiji 玉函山房詩集 (collected poems), Yueling qishier hou shi zizhu 月令七十二候詩自注, Mugengtie 目耕帖, Zhuruyi 竹如意, and Hong'ouhuaxuan quanpin 紅藕花軒泉品.
